US weighs easing sanctions on shadow fleet tankers

As of 14 October the administration is discussing whether to let previously sanctioned tankers carry unsanctioned oil, according to a US official who spoke to Reuters. The aim is to bring down record tanker freight rates; sanctions on Russian and Iranian oil stay in place.

Location: WASHINGTON

According to the Reuters report carried by gCaptain, the talks focus on allowing shadow fleet vessels, sanctioned for carrying Russian, Iranian and Venezuelan oil, to move crude and products that Washington does not sanction. Companies wishing to use the ships would apply to the US Treasury; no decision has been finalised. Energy Secretary Chris Wright raised the issue in a video message to the World Petroleum Congress in Riyadh. The move follows the Russian diesel licence, valid until 7 April, and comes ahead of the US midterm elections on 3 November.

The shadow fleet is the pool of tankers that operate uninsured or under opaque ownership to evade sanctions. Energy Aspects says easing would not cut freight rates meaningfully but could add a few tankers to Hormuz transshipment runs. In its view, most tankers sanctioned for Russian or Venezuelan links were already trading actively over the past 3 months. Industry sources say EU and UK rules on ship insurers will remain in force. According to Oilprice, the news pulled Brent down to $104.39 on the morning of 15 October; the December Brent contract settled the day at $105.92.

Talay assessment

Bottom line

For the first time, Washington is weighing a vessel-level relaxation of its sanctions regime to ease price pressure, the second concession after the Russian diesel licence. The physical impact looks modest, because most sanctioned tankers are already working and European insurance rules remain in place. The real message is that, ahead of the election, price is taking precedence over sanctions.

Likely effects

Tanker freightUncertainWeeks
Energy Aspects sees a limited effect: a few tankers could join Hormuz transshipment runs, but freight will not fall meaningfully from record levels.
Sanctions regimeNegative1–6 months
Loosening the vessel list weakens the deterrent effect of sanctions and could later hand legal cover to owners with Russian or Iranian links.
Transatlantic divergenceNegative1–6 months
With EU and UK insurance rules still in force, US easing stays unilateral and sanctions alignment with Europe weakens.

Possibilities, ranked

1
A narrow licence is issued45%
The Treasury publishes a narrow, application-based licence and the freight impact stays small.
Watch: General licences published by the US Treasury's OFAC
2
The debate goes nowhere40%
Pushback from Congress and Europe means no decision before the midterms.
Watch: Progress of senators' moves against the Russian diesel licence
3
Broad easing15%
Easing extends to sanctioned oil itself, and Russian and Iranian barrels reach the market more easily.
Watch: Changes to the sanctions list targeting Russian or Iranian oil
